CAR-COUPLING.

SPECIFICATION forming part of :Letters Patent No. 518,684, dated April 24, 1894.

, Application filed November 18, 1893. Serial No, 491,360. No model.)

To alt whom it may concern:

Be it known that I, FRANK H. YINGER, a

citizen of the United States of America, residing at Zanesville, in the county of Muskingum and State of Ohio, have invented certain new and useful Improvements in Car-Couplers, of whichthe followingisaspecificatiomreference being bad to the accompanying drawings.

Thrsinvention relates to certain new and useful 1m provements in automatic car couplings, also to mountings for the same.

The object is to provide novel means in a coupling of this class by which the link shall beautomatically retained in an elevated positlon, thereby doing away with even the slightest manual adjustment of the link and the consequent risk incurred.

A further object is to employ a novel arrangement of parts by which the coupling shall be normally held in readiness to receive and automatically lock the link in engagement, without preparatory manual adjustment of either the coupling or the link.

A further object is to provide in combination with an automatic coupling, means for yleldlngly and at the same time firmly mountmg the same, thereby relieving to a great extent the cars from the objectionable jolting, jjarrlng, &c., incident to travel at the present With these and other objects in View, vallOllS combinations and arrangements of parts are employed, which will be hereinafter more fully set forth and specifically pointed out in the claims.

In describing the invention in detail, reference is had to the accompanying drawings forming part of this specification and wherein like letters indicate corresponding parts in the several views, in which- Figure 1. is a horizontal sectional View, showlngthe manner of mountingthe coupling. Fig. 2 1s a transverse sectional view, taken on the line -maa-of Fig. 1. Fig. 3. is a vertical sectional view of the drawhead, showing the same in an operative position, preparatory to coupling. Fig. 4. is a similar view, in horizontal section, taken on the line yy of Fig 3 and showing the link by dotted lines.

In the drawings :A, denotes the drawhead; 3, the drawbar; G, the spring buffer or cushion for taking up longitudinal shocks, &c.; D, D, spring buifers or cushions for taking up lateral jarring; E, an elevating device for adjusting the drawhead vertically; and F, a

device for adjusting the head laterally.

As the general exterior form of the drawhead and bar are commonly known in the art, a detail description thereof will not be given, sufiice it to say, the bar is recessed to receive a transversely disposed bar which latter had formed therein a series of openings to receive stop-pins and works in guide slots -gg of the beams G of the car floor. Thus theinner end of the draw bar is capable of ready adjustment and may be retained practically true and against wabbling, under all conditions. Projecting above and below, and pivotally secured to the inner extremity of this draw bar by a bolt b which latter also enters a central.

opening of the bar are apertured ears or lugs -c c of a head -c-. This head forms a part of a rearwardly extending rod c which is encircled by a spiral spring -c acting against shoulders -c --e formed by said head and a transversely disposed bar -e. Through this bar e-- the rod passes and is provided at the projecting end with an opening to receive a bolt or pin The bar -e is slidingly mounted in vertical apertured guides -e e which project inwardly from the floor beams Gand is secured by means of bolts --e e at any suitable height.

Referring to Fig. 2, -0Z represents an intermediate or central enlargement of a rod -d on which is pivotally mounted a bolster d recessed at d to receive the drawbar, the latter being slidingly mounted therein. The rod d passes loosely through openings -gg of the floor timbers -GG- and is provided at or near the extremities with tensioning nuts -d -d which serve as shoulders to confine spiral springs cld encircling said rod and acting against the timbers, as shown.

Referring to Figs. 3 and 4, the draw-head A is shown chambered as at a. and provided with a flaring mouth -a On the bottom of this mouth within the head and formed by a direct continuation of the flare the rear of the detent, thus as the operating crank -a is thrown, motion will be transmitted to the detent through the common shaft a causing a rear-upward movement of the detent, which latter engages and carries the weight rearwardly so as to allow the link to become readily disengaged.

- The operation will be readily understood from the above description.

Having fully described my invention, What I claim as new, and desire to obtain by Letters Patent, is-

1. The combination with a draw-head and bar as described, of the bolster in which the draw-bar is mounted, and a transverse rod carrying said bolster for th e purpose specified.

2. The combination with a drawhead and bar, of means for adjusting said head trans versely and vertically, and the recessed bolster, in which the draw bar is sliding-1y mounted for the purpose described;

3. The combination with a drawhead and bar,-of the bolster pivotally mounted on a rod carrying tension nuts which serve as shoulders, and the spiral springs inclosing said rod for the purpose described;

a In testimony whereof I affix my signature in presence of two witnesses;

FRANK H. YINGER.
